A comparative hydrodynamic study of artificial heart valves with spherical, hemispherical and lentil-shaped obturative elements has been carried out under the non-stationary conditions. The valves resistance coefficient is higher in the lentil-shaped valves. With the increase of pulse rate the stroke volume of the valves of all the types drops, and the regurgitation increases.
在非稳态条件下，对具有球形、半球形和扁豆形阻塞元件的人工心脏瓣膜进行了比较流体动力学研究。扁豆形瓣膜的瓣膜阻力系数更高。随着脉搏率的增加，所有类型瓣膜的搏出量下降，反流增加。
